Layer Selection

When running egldevice versions of the graphics samples, applications can select the overlay where to direct the sample output. Only one application can run per overlay, and the number of overlays per display head varies depending on the hardware configuration.

-layer <depth>

For example, on NVIDIA DRIVE? AGX Platform, valid values are -layer [0|1] for -dispno [0|1] and -layer 0 for -dispno [2|3].

Here, dispno is the display number that is assigned serially from 0 through 3 for the four displays on a DRIVE AGX SoC.
